        <p>UTFGrids can be used to output highly optimized feature "hit grids."
        The UTFGrid encoding scheme encodes interactivity data for a tile in a
        space efficient manner. It is designed to be used in browsers for
        interactive features like displaying tooltips without having to hit the
        server for an "info query."
        </p>

        See the <a href="utfgrid.js" target="_blank">utfgrid.js source</a> for 
        detail on using UTFGrids in OpenLayers.  For more info, view the
